Abstract: 1,249,437. Pneumatic separators. T. SATAKE. 8 April, 1970 [25 April, 1969; 28 Jan., 1970], No. 16737/70. Heading B2H. In a winnowing apparatus for separating husks from husked grain, e.g. rice, a mixture of husks and husked grain from a husker 9 passes through an opening 16 in a top wall of the apparatus and falls by gravity through a vertical passage defined by wind-shielding plates 17, 18. Currents of air produced by air sucked in by means of a fan 36 through an open front side wall, which may be provided with a screen 15, and through passages 19, 20, 21 pass transversely through the mixture stream. The husks and the unripe husked grain pass with the air into a winnowing chamber 24 while the fine husk grain falls straight down into a channel 23 provided with a discharge screw conveyor 22 In the chamber 24 the unripe grain hits against an inclined plate 25 and descends along the surface thereof into a gathering channel 26. The husks are entrained by the air through a passage 28 defined between the top wall of the apparatus and an uppermost curved portion 27 of the plate 25 and enter with the air into settling chamber 29 which is outwardly bound by a curved rear side wall 13 of the apparatus. Due to the curvature of the wall 13 and of the plate portion 27 the mixture of air and husks is subjected in the chamber 29 to centrifugal separation. The air passes inwardly to an opening 32 which is connected to the fan 36 by a conduit 37 air-tightly fitted through a downwardly inclined guide plate 33, 34. The husks are thrown by centrifugal force against the curved wall 13 and slide down the latter into a collecting channel 31 from which they are discharged by means of a screw conveyor 30 into a central conduit 41, Fig. 5, connected to a discharge conduit 38 for the fan. A rotary valve 40 in the conduit 41 prevents air being blown back from the conduit 38 to the settling chamber 29. The conduit 38 is connected to a cyclone (42), Fig. 1 (not shown), in which the husks are separated from the air. In a modification, Fig. 4 (not shown), the channels 23 and 26 are interconnected by a screen (43) instead of a solid wall so as to provide an additional passage for the air.

Title: Improvements relating to the manufacture of dry animal protein substances
IPC: A23J1/06
Filed: 1935-06-11
Abstract: <PICT:0457831/IV/1> Dry animal protein substance is obtained from blood, egg contents, or aqueous extract of bones or hide by mixing therewith a solvent whereby the water is dissolved and the protein substance is precipitated, the precipitate being separated from the solvent and being treated either by a further application of the same solvent, or by the use of another more volatile solvent which will dissolve the remaining mixture of water and first solvent, the solution being again removed from the precipitate which is dried by exposure to air.  In the manufacture of edible dried blood, the blood after being drawn from an animal is mixed with acetone or alcohol which is afterwards drained off, the residue being mixed with diethyl ether.  The mixture of ether and small traces of acetone or alcohol and water is drained off and the sludge left is exposed to a current of air which vaporizes the remaining solvent. In the preparation of dried blood albumen for use as a fixative in calico printing and as an adhesive, the blood is separated into serum and clot and the serum is brought to an apparent pH value of 8 by addition of an alkaline substance, preferably trisodium phosphate.  The serum is cooled to 0 DEG  C. and is mixed with cooled ethyl alcohol.  The alcohol is run off and replaced by cooled ether which is subsequently decanted, the residue being dried by a current of air.  In a similar manner when it is required to obtain egg albumen which is dispersable in water, the invention is modified by the addition of acid or alkaline substances to the protein substance and the first solvent so that neither the liquid nor the sludge shall have the hydrogen ion concentration corresponding to the isoelectric point of the protein.  In the manufacture of dry edible gelatine a solution of gelatine is delivered on to a rotating cooling drum A on which it forms a gel. The gel is carried into a vat C of alcohol which reduces the water content of the film so that it is easily detached by a doctor D. It is then carried over a guide pulley to a vat E containing diethyl ether and afterwards passes through a tunnel F where a draught of air removes the last traces of solvent.

Abstract: 1,069,423. Coating apparatus. AEROSTYLE Ltd. April 28, 1964 [April 29, 1963], No. 16834/63. Heading B2L. In electrostatically depositing powdered insulating material on an article, a stream of air or other gas and the material is forced through a duct made of insulating material, which duct causes the material to follow a tortuous path therewithin so that the particles of powdered material are brought into frictional contact with the walls of the duct and thereby acquire an electric charge, and the powdered material is then directed at the article. In the embodiment shown container 11 with pressure tight lid 12 contains the powder to be sprayed and has means (not shown) by which powder may be sucked into a tube, the latter being connected to an insulating hose 14 wound on a central stem. The end portion 17 of the tube leads to a nozzle by which the powder can be directed on to articles to be sprayed. The coiled formation of the tube ensures that the particles of powder strike the inner surface of the tube bore and generate friction so that they become electrically charged. The article'to be sprayed is maintained at a suitable potential such that the particles are attracted by the article and the article is preferably maintained at a temperature to cause the particles of powder to fuse together.
